Made it into a library:
http://github.com/medecau/QuadEncoder -
I have the some example code for the Arduino that does a decent job figuring out where and how much is being turned on the encoder.
Take a look here:

This is a class IIIa, up to 5 mW output power.
A class IIIb with output power from 6mW to 500mW would be able to cause light skin burns[1].
I'd say if you want to get paper or some other material cut you would need some very powerful laser beams.
